# Approved Operators

### **What are Approved Operators in PNS?**

In PNS, approved operators are like trusted friends you give special permissions to help manage your .pls domain names.

### **Two Types of Operator Approvals**

1. **Full-Control Operator Batch Approvals**:
   * Think of this like giving a friend a master key to all your domains.
   * When you use a special method (`setApprovalForAll`), you're telling the PNS system, "Hey, this friend can take care of all my .pls domains."
   * This is usually used by big NFT marketplaces to help manage lots of domains at once.
2. **Name-Specific Subname Renewal Manager Approvals**:
   * This is like giving a friend a key to just one specific room in your house.
   * You use a different method (`ERC-721 approve`) to choose a "Subname Renewal Manager" for just one of your domains.
   * This manager can't do everything - they can only help extend the expiry date of subdomains under that one domain.
   * If you decide you always want this friend to manage renewals, you can "lock" this choice. Once locked, you can't change this manager.

### **What Happens When You Change Things?**

* If you decide to unwrap (remove the NFT wrapping) your domain, or if it expires and someone re-registers it, the approval for the renewal manager resets.
* If you transfer your domain to someone else, the renewal manager stays the same only if you've locked the choice. Otherwise, it resets too.

### **Example: Setting Up a Subname Registrar Contract**

* Imagine you want to let people register their own subdomains under your domain. You can set up a special contract (like a program) to do this for you.
* First, you give this program full control over your domain so it can create subdomains.
* Then, you can also set it up to manage renewals by making it a renewal manager and locking this choice.
* You can always take back the full control if you need to, but the renewal part will stay with the program forever.

### **What This Means for You**

* You don't have to give your domain to someone else to manage these things. You just give them special permissions.
* This helps you manage your domains more easily and make sure they keep working the way you want.
